Description
898788-89-1 (4-Chloro-3-fluorophenyl){3-[(4-methylpiperazin-1-yl)methyl]phenyl}methanone DTXSID80643434 (CAS 898788-89-1) is a high-purity analytical reference standard with the molecular formula C19H20ClFN2O and a molecular weight of 346.83 g/mol.
The molecular framework of 898788-89-1 (4-Chloro-3-fluorophenyl){3-[(4-methylpiperazin-1-yl)methyl]phenyl}methanone DTXSID80643434 (C19H20ClFN2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
